Runny nose. Itchy, watery eyes. Sneezing. If you don’t have allergies, you probably know someone who does. The number of people with allergies, including food allergies and eczema, is increasing. What is going on?

A medical anthropologist describes how our hygiene habits, our diets, and our polluted environment are irritating our bodies. Also, the case for skipping your shower. Is skin healthier when we stop lathering?

Guests:

James Hamblin – Preventive medicine physician and a lecturer in public health at Yale and author of Clean: the New Science of Skin

Theresa MacPhail – medical anthropologist, professor of science and technology studies at Stevens Institute of Technology and author of Allergic: Our Irritated Bodies in a Changing World.

The powerful gene editing tool CRISPR is already being tested on animal and plant cells. It has even been used on humans. How might this revolutionary tool change our lives? On the one hand, it could cure inherited diseases and rid the world of malaria-spreading mosquitoes. On the other hand, scientists using it are accelerating evolution and introducing novel genetic combinations that could transform our biological landscape in unforeseen ways. We explore the ramifications of this revolutionary technology.

Guests:

Nathan Rose – Molecular biologist and head of malaria programs at U.K. based biotech company, Oxitec.

Hank Greely – Law professor and director of the Center for Law in the Biosciences at Stanford University and author of “CRISPR People: The Science and Ethics of Editing Humans.”

Antonio Regalado – Senior Editor for Biomedicine, MIT Technology Review.

A canopy of stars in the night sky is more than breathtaking. Starlight is also an important tool that astronomers use to study our universe. But the growth of artificial light and light pollution are creating dramatic changes to the nighttime environment. Let your eyes adjust to the dark as we travel to a dark sky reserve to gaze upon an increasingly rare view of the Milky Way and explore what we lose when darkness disappears.  

Guests:

Kim Arcand – Visualization scientist & emerging tech lead, NASA's Chandra X-ray Observatory and author of “Light: The Visible Spectrum and Beyond".

Don Jolley – Teacher of Math and Sciences at the Bolinas School in Marin, California who has been leading dark sky tours for three decades.

Christopher Kyba – Interdisciplinary Geographic Information Sciences Research Fellow at Ruhr University Bochum.

We are closer than ever to finding aliens according to astrophysicist Adam Frank. He isn’t alone in his optimism. Over the last two decades, the tools used to search for extraterrestrials have been advancing mightily. Where we were once only monitoring with radio telescopes, we are now actively looking for bio and technosignatures on exoplanets. Find out why scientists think new technology may be a game changer in the hunt for life off Earth.

Guest:

Adam Frank – Astrophysicist and author of a new book “The Little Book of Aliens”

Electricity plays an important role in our everyday lives, including allowing our bodies to communicate internally. But some research claims electricity may be used to diagnose and treat disease? Could electric pulses one day replace medications?

We speak with experts about the growing field of bioelectric medicine and the evidence for electricity’s healing abilities. Their comments may shock you.

Guests:

Sally Adee – Science journalist, author of “We Are Electric: Inside the 200-Year Hunt for Our Body’s Bioelectric Code, and What the Future Holds"

Samantha Payne – Assistant Professor of Biomedical Sciences at University of Guelph

Kevin Tracey – Neurosurgeon and President of the Feinstein Institute at Northwell Health

Before everything could come up roses, there had to be a primordial flower – the mother, and father, of all flowers. Now scientists are on the hunt for it. The eFlower project aims to explain the sudden appearance of flowering plants in the fossil record, what Darwin called an “abominable mystery.”

Meanwhile, ancient flowers encased in amber or preserved in tar are providing clues about how ecosystems might respond to changing climates. And, although it was honed by evolution for billions of years, can we make photosynthesis more efficient and help forestall a global food crisis?

Guests:

Eva-Maria Sadowski - Post doctoral paleobotanist at the Museum für Naturkunde, Berlin

Regan Dunn - Paleobotanist and assistant Curator at the La Brea Tar Pits and Museum

Royal Krieger - Rosarian and volunteer at the Morcom Rose Garden, Oakland, California

Ruby Stephens - Plant ecology PhD candidate at Macquarie University in Australia, and member of the eFlower Project

Stephen Long - Professor of Plant Science, University of Illinois

They’re cute and cuddly. But they can also be obnoxious.

Science writer Mary Roach has numerous tales about how our animal friends don’t always bow to their human overlords and behave the way we’d want. The resulting encounters, such as when gulls disrupt the Vatican’s Easter mass, make for amusing stories. But others, such as wolves threatening farmers’ livestock, can be tragic.

We hear what happens at the messy crossroads of human and wildlife encounters.

Guest:

Mary Roach – Author of bestselling nonfiction books, most recently “Fuzz: When Nature Breaks the Law.”

Before you check your social media feeds today. And post. And post again. And get into an argument on Twitter, lose track of time and wonder where the morning went, consider that social media was never a natural way to socialize.

A cultural anthropologist weighs in on the evolutionary reasons humans can’t thrive on social media. And we hear about the signs that social media is on its way out. If that’s the case, what’s next? 

Guests:

Max Fisher – Reporter for The New York Times, author of “The Chaos Machine: The Inside Story of How Social Media Rewired Our Minds and Our World”

Douglas Rushkoff – Professor of media theory and digital economics at City University of New York, and author of “Survival of the Richest: Escape Fantasies of the Tech Billionaires”

It’s not just facts that inform our decisions. They’re also guided by how those facts feel. From deciding whether to buckle our seat belts to addressing climate change, how we regard risk is subjective. In this extended conversation with an expert on the psychology of risk, find out about our exaggerated fears, as well as risks we don’t take seriously enough. Meanwhile, while experts warn society about the dangers of self-aware AI – are those warnings being heeded?

Guest: 

David Ropeik – Professor emeritus Harvard University, and expert on the psychology of risk

Ever heard of a beauty quark? How about a glueball? Physics is full of weird particles that leave many of us scratching our heads. But these tiny particles make up everything in the quantum world and in us and are the basis of the fundamental scientific theory called The Standard Model. But it doesn’t explain everything. It can’t account for dark matter or dark energy, for example. We find out whether new physics experiments might force us to rewrite the Standard Model. Plus, we discuss a NASA proposal to fly spacecraft close to the sun in search of new physics.

Guests:

Phil Plait – Aka the Bad Astronomer, former astronomer on Hubble, teacher, lecturer and debunker of conspiracy theories. He is also the author of a new book “Under Alien Skies: A Sightseer’s Guide to the Universe.”

Harry Cliff – Particle physicist at the University of Cambridge who works on the LHCb experiment at the largest particle physics laboratory in the world, CERN. He is the author of: “Space Oddities, The Mysterious Anomalies Challenging Our Understanding of the Universe.”

Slava Turyshev – Research scientist at NASA’s Jet Propulsion Laboratory.
